Teacher makes student can understand train knowledge preferably and simply obtain its ratio of gear at classroom teaching, needs a kind of teaching aid that can cause the learning interest of student.
Utility model content
In order to overcome the defect existed in prior art, the utility model provides a kind of save space, and material saving is convenient, flexible, and make student's intelligible multifunctional gear driving device easy to learn, its technical scheme is as follows:
A kind of multifunctional gear driving device, rotated by one end of driven by motor first gear 1, first gear 1 other end is connected to the 5th gear 6 one end, 5th gear 6 connects the 6th gear 7, 6th gear 7 and the 3rd gear 4 are coaxially connected to the first tooth bar 3, the other end of the 5th gear 6 connects the tenth gear 11, tenth gear 11 is connected to the 9th gear 10, 9th gear the 10 and the 11 gear 13 is coaxially connected to the second tooth bar 12, second gear 2 is embedded on the 4th gear 5, and second gear 2 one end connects the 13 gear 16, 13 gear 16 be connected tooth bar 14 coaxial with the 12 gear 15, in planet carrier, the first gear 1 is driven to rotate by electric machine rotation, first gear 1 connects the 5th gear 6 one end, 5th gear 6 other end connects the tenth gear 11, the 7th gear 8 in one end connected row carrier of the tenth gear 11, 7th gear 8 one end connects octadentate and takes turns 9 one end, 9th gear the 10 and the 11 gear 13 is coaxially connected to the 3rd tooth bar 14.
The beneficial effects of the utility model:
(1) the utility model brings a kind of mystique to student, shows effect in compound gear train and function to student, is no longer only character introduction complicated on textbook book, student can be allowed in this device more easily to get more information about the transmission of gear.
(2) can gear be realized, make student can obtain multiple ratio of gear in different situations.
(3) can when realizing longer-distance transmission conserve space, save material.
(4) larger ratio of gear can be obtained under square one.
In a word, the utility model volume is little, and structure is simple, takes up room little, easy to use on classroom.Student is allowed to be easier to understand gear-driven process and ratio of gear, these works are introduced classroom, regulate classroom atmosphere, training student produces keen interest and hobby to machinery, the creativity consciousness of training student with start the ability that practice innovation makes some mechanical opuscules more educational undertaking contributed.Except using on classroom, also can be used for increasing its ratio of gear in all kinds of mechanical industry, have good market outlook.
Accompanying drawing explanation
Fig. 1 is the structural representation of multifunctional gear driving device.
Specific embodiments
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in more detail.
The utility model adopts the minimum plank of area as base plate, and five blocks of transparent organic glass are made into cuboid-type box as face.The space that dais is too many can not be taken, and facilitate teacher to carry to go to class.Multifunctional gear driving device is totally combined by fixed shaft gear train and cyclic train.During fixed shaft gear train transmission the cogged axis of rotation position that has it fixing, it can not only do longer-distance transmission, obtains larger ratio of gear, can also turning to by change driven shaft, thus obtain multiple ratio of gear.Utilize this good feature of fixed shaft gear train just, in " multifunctional gear transmission ' black box ' ", we are fixed on fixed shaft gear train revolving shaft on box front-back, can realize longer-distance transmission, thus enable whole mechanical driving device obtain larger ratio of gear.But when needing larger ratio of gear between diaxon, no doubt can realize with the fixed shaft gear train of multi-stage gear composition, but due to increasing of axle and gear, complex structure can be caused, if only use a pair gear drive, the size of two-wheeled will be made to differ greatly, and contour dimension is huge, so the ratio of gear of a pair gear is generally not more than 8.When needing larger ratio of gear, just should adopt train to realize.Particularly adopt cyclic train, available little gear, compact structure, obtains very large ratio of gear.And under main drive shaft turns to constant condition, utilize train can change turning to of driven shaft, thus implement device turn to transmission.
Fixed shaft gear train scenario-frame designs
Because designing requirement, need to adopt fixed shaft gear train well to control the direction of transmission.For fixed shaft gear train design attitude we devise following scheme.
Adopt driving wheel and engaged wheel far to obtain larger ratio of gear, but let us adopt train to carry out transmission, loading onto several little gear, just can well control the direction of transmission in that way and conveniently observe between main drive shaft and driven shaft.
With reference to Fig. 1, the utility model in embody rule process,
Can be rotated by starter motor, drive the first gear 1 to rotate, device comes into operation.
In (1) two gear, meshing dead axle transmission is shown: establish driving wheel to be the 4th gear 5, engaged wheel is the second gear 2, and the 3rd gear 4 wherein, the 5th gear 6, the 6th gear the 7, the 12 gear 15 with the 13 gear 16 for transition is connected gear, at this moment the first tooth bar 3 and the 3rd tooth bar 14 are display device, the movement of the first tooth bar 3 mainly reflects the rotating speed of 5-gear and turns to, and the movement of the 3rd tooth bar 14 mainly reflects the rotating speed of the second gear 2 and turns to.By the movement of these two tooth bars, directly can reflect that the interior meshing dead axle of the second gear 2 and the 4th gear 5 conveys feelings condition.
(2) two outer meshing dead axle transmission of gear are shown: establish driving wheel to be the 5th gear 6, engaged wheel is the tenth gear 11, and the 3rd gear 4 wherein, the 6th gear 7, the 9th gear 10 with the 11 gear 13 for transition is connected gear, at this moment the first tooth bar 3 and the second tooth bar 12 are display device, the movement of the first tooth bar 3 mainly reflects the rotating speed of the 5th gear 6 and turns to, and the movement of the second tooth bar 12 mainly reflects the rotating speed of the tenth gear 11 and turns to.By the movement of these two tooth bars, directly can reflect that the outer meshing dead axle of the 5th gear 6 and the tenth gear 11 conveys feelings condition.
The above; be only the utility model preferably embodiment; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen in protection domain of the present utility model.
